This change is to implement a new function "any2array", which will take any
argument or arguments and create an array which contains it. If the argument
is a single array then it will be returned as-is. If the argument is a single
hash then it will be converted into an array. Otherwise (if there are more than
one argument, or the only argument is not an array or a hash) the function will
return an array containing all the arguments.
This is a bit more heavy-handed than I might like, but it does appear to
do the right things:
* accepts numeric input appropriately, truncating floats
* matches string input against a regex, then coerces number-looking
strings to int
* makes a best effort to coerce anything else to a string, then subjects
it to the same treatment
* raises an error in the event of incorrect number of arguments or
non-number-looking strings
I've also included some additional unit tests.
No more coercing to String and regex matching. Instead, we now coerce
to Integer at the beginning or raise an error if we cannot coerce to
Integer.
A consequence of this change is that the function will now accept
blatantly non-numeric strings as input, and return false. This seems a
bit goofy to me, but it's how String#to_i works. If we really don't
like this, then I'm open to suggestions.
Puppet passes numbers as String to functions, but it makes more sense to
compare them as Numeric.
But sometimes Puppet passes them as the wrong type, see:
https://projects.puppetlabs.com/issues/19812
When prefix and suffix did error checking with positional arguments,
they would not report the position of the argument that failed to
validate. This commit changes the messages to indicate which argument
failed.
This function provides a simple wrapper around
Puppet::Parser::Functions.function for access within Puppet manifests.
This will allow users to check whether or not a plugin or functionality
such as hiera is installed on the server.
This reverts commit f7a18189ec, reversing
changes made to 36a7b29630.
I'm reverting this change because of concerns raised by Peter Meier that
it duplicates the "in" operator in the DSL. The "in" operator is new
information that I did not posses when I made the decision to merge.
Because of this new information I'm un-merging and continuing the
discussion in the comments of
https://projects.puppetlabs.com/issues/19272
Reference: GH-130
It is exceptionally difficult to determine if an array contains an element matching a specific value without an iteration or loop construct.
This function is the Puppet equivalent of Array.includes?(foo) in Ruby. The implementation is a verbatim copy of has_key() with the minor modifications needed to support arrays instead of hashes.
Without this patch applied there is no easy way to append one array to
another. This is a problem because it is often desirable to join two
arrays without flattening the contents into a single, one dimensional
array.
This patch addresses the problem by adding a `concat()` function which
takes two arguments. The arguments will be concatenated together and a
new array returned to the caller.

As far as i know there's no other puppet-dsl-like way to get parameter of
defined resource, so that's why i implemented getparam function, which takes
resource reference and parameter name and returns parameter value.
Here's another example why this function is really useful:
define config($path, $config_param1, $config_param2) { }
define example_resource($config) {
$path = getparam($config, "path")
notice("Path is $path")
}
define example_resource2($example_resource, $config = getparam($example_resource, "config")) {
$config_param1 = getparam($config, "config_param1")
notice("Config parameter is $config_param1")
}
define example_resource3($example_resource, $config = getparam($example_resource, "config")) {
$config_param2 = getparam($config, "config_param2")
notice("Config parameter is $config_param2")
}
class test_getparam {
config { "config_instance":
path => "/some/config/path",
config_param1 => "someconfigtext1",
config_param2 => "someconfigtext2",
}
example_resource { "example_resource_instance":
config => Config["config_instance"]
}
example_resource2 { "example_resource_instance":
example_resource => Example_resource["example_resource_instance"]
}
example_resource3 { "example_resource_instance":
example_resource => Example_resource2["example_resource_instance"]
}
}
class { "test_getparam": }

Add test/validation for is_float if created from an arithmetical operation
Add test/validation for is_integer if created from an arithmetical operation
Add test/validation for is_numeric if created from an arithmetical operation
Its often the case that modules need to install a handful of packages.
In some cases its worth breaking these dependencies out into their own
modules (e.g., Java). In others it makes more sense to keep them in the
module. This can be problematic when multiple modules depend on common
packages (git, python ruby, etc). ensure_resource was a good first step
towards solving this problem. ensure_resource does not handle arrays and
for 3 or more packages stamping out ensure_resource declarations is
tedious.
ensure_packages is a convenience function that takes an array of packages
and wraps calls to ensure_resource. Currently users cannot specify
package versions. But the function could be extended to use a hash if
that functionality would be useful.
This commit adds a function that joins each of a hash's keys with that
key's corresponding value, separated by a separator string. The
arguments are a hash and separator string. The return value is an
array of joined key/value pairs.
Previous to this commit, the delete function only acted on
arrays. This commit adds the same functionality for hashes and strings
in the obvious way: delete(h, k) would delete the k key from the h
hash and delete(s, sub) would delete all instances of the sub
substring from the s string.
